FIXING DEVICE, IMAGE FORMING APPARATUS, FIXING METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

摘要

A fixing device includes a first rotation member, a fixing member, a determining unit, and a magnetic field generating unit. The first rotation member rotates around a first axis. The fixing member includes a second rotation member which rotates around a second axis while being in contact with the first rotation member, and which generates heat by using electromagnetic induction in an alternating-current magnetic field. The fixing member fixes an image onto a medium in a region where the first rotation member and the second rotation member come into contact with each other. The determining unit determines whether or not a current state is a certain state where the medium or an image formed on the medium is passing through the region. The magnetic field generating unit generates an alternating-current magnetic field in a space including the second rotation member.
